Application filed pctober 20, 1917. Serial No. sm-is.

To all whom it may concern:

Be it known that 1, MIKE KnAcULLAcz, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Switch-Throwing Mechanism, of which the following is a specification.

This invention relates to switch throwing mechanism and more particularly to the mechanical type and has for its primary object to provide mechanism of this character that may 'be readily operated by the passing carwithout the necessity of the car coming to a standstill.

An object, of the invention is the novel arrangement of the drums, pulleys and cables so that when. force is brought to bear upon the cable it will tend to straighten out, thus throwing the switch point.

lVith these and other objects in view the invention will he better understood from the following detailed description taken in connection with the accompanying drawings wherein:

Figure 1 invention.

Fig. 2 is a detailed view of the trip.

Fig. 3 is a similar view connected to a signal device.

Figs. i and 5 are views of the ear carried mechanism. I

At the start I wish to call attention to the fact that althoiigh the invention is shown applied to the Y type of switch the same may be used with other forms of switches. In this particular instance a plate 1 rigidly connects the switch points Quad 3 together so that they may move as a unit. The intermediate portion 4 of the plate is depressed so that the pulleys 5 supported thereby may beaccommodated in a position slightly be is a diagrammatic view of the .low the rails, so that the cables 6 and 7 may,

- pass under the rails as clearly shown in the drawings. Each cable has its ends secured to drums 8 that are so arranged that approximately one-half of the cable a is ranged at an angle with the other half 6 with the result that when the cable is pulled it will tend to straighten with the result that the plate l will be given a rectilinear movement and by its connection. with the switch points will open one switch pointand close the other. Each drum is mounted upon a shaft, 9 to one end oi which is secured a trip 10, projecting above the rails as clearly shown in Fig. 2 and held in a vertical position by spring 11. The

movement of the trip is limited by a lug 12.

shown in Pig. 3.

Iffound advantageous in practice the trip may be formed with an extension 13 that has a link connection 14. with the crank portion the shaft 16 which supports a signal 17. The advantage of this construction is that a visual indication is given the operator of the car as to the condition of the switch points. Any suitable mechanisms may be arranged upon the car for striking the trip and for the purpose of illustration I have shown a pneumatic apparatus consisting of a cylinder 18 in which works a piston 19 having secured thereto a rod 20 adapted when in a protuding position to strike the trip- 10. For moving the piston in either direction 1' provide the valve 21 and pipe connections 22 and iiif'such a manner that air may act in one portion of the cylinder while air is exhausted from the other portion.

From the foregoing description it wili be seen that by simply operating the valve 21 the rod 20 may be moved in a position to strike the trip l0 for throwing the switch point in a position to allow the car to travel in the proper direction.

Having described my invention what I claim is:

Switch throwing mechanism comprising a, rod pivotally connected to the switch poinm, a pulley mounted on the rod a shaft arranged to each side of the pulley and switch point, a drum on each shaft a cablehaving its ends secured to the drum and the intermediate portion arranged at an angle and pressed against said pulley in a manner set forth, a tri connected to each shaft and a spring holding the same in an upright position.

In testimonv whereof I atfix my signature.

MIKE KRAGULLACZ.
